Re: error in calendar

[Richard Stallman]

    It may not have to do with the compiler at all, but with a variable
    (mark-diary-entries-in-calendar) being reset by the evaluation, which
    caused the problematic code not to be executed.

I don't understand.  Could you explain what that means?
Anyway, why does this resetting effect differ depending
on whether the function is compiled?

Did you try compiling vs interpreting *just this function*
or *the whole file*?

    It may have to do with customisations.

They may be relevant somehow, but didn't you try both forms of the
function with the same customisations?
